I recently had to rebuild my Grendel AR. I switched to an 18" 1:9 Black Hole Weaponry mid-length barrel, so all of my data for the 20" 1:8 barrel is out the window.
I have a shooting competition on the near horizon and will not have the time to develop all of the dope required, so I am hoping for a little help, at least for comparative purposes.
Ranges will be 200 yards up to 1200 yards, and I will be running a YHM 7.62 suppressor. The only ammo I will be using will be the Hornady 123 A-Max (because that is all I have.)
Any data will help, but muzzle velocity and any bullet drop/drift data (with associated temp, barometer, etc at time of zero) out to 1200 yards will be the most helpful. I will be working from a 100 yard zero.
Thanks for your help.
